Installation and Commissioning
The connection diagram shows the sample connection of the multi-input/output as a valve
coupler
Cable Position Fixture
The R8D0-MIO* electronics provides special fixtures for cable ties. To keep the cabling in a
safe position, use the fixtures with cable ties.
Cable tie width: up to 4 mm
Using Mechanical Switches
If mechanical contacts are used as valve final position feedbacks, observe the following. The
lead breakage and short circuit monitoring can be used after adding series and parallel
resistors in the lead. In this case the prerequisites are:
■
1 x 1-kOhm series resistance for monitoring short circuit
■
1 x 10-kOhm parallel resistance for lead breakage detection

F2 Housing Degree of Protection
The following section contains information concerning the installation and sealing of the cable
glands and the housing cover.
Fixing the Housing Cover
Before closing the housing cover: Visually inspect the housing for any visible signs of damage
on the cover seal. If damaged, replace the seal with an original seal wear part.
Tightening torque for the screws of the housing cover: 2.5 Nm

Danger!
Explosion hazard or danger to life from inadequate installation of cable glands
If you do not install cable glands according to the instructions given in the instruction manual,
this can generate sparks that can ignite the surrounding potentially explosive atmosphere.
Furthermore, insufficient installation practice can result in electric shock.
Ensure you carry out any cable gland installations in accordance with the instructions given in
the instruction manual.
